The contact lens story is the only thing here that matters. Twenty-minute custom optics printing isn't incremental—it's a potential category killer for an industry built on weeks-long supply chains and one-size-fits-most manufacturing. Everything else is noise: filament deals are commoditized (Kingroon at $6.50/kg is fine but forgettable), firmware bumps are expected maintenance, and that "customized cover" is just cutting vinyl with extra steps. Watch the lens work obsessively; ignore the rest until someone actually commercializes it at scale.
